Instrument used is final test with indicator concept of comprehension form of the test used is essaywith totaling 9 item question. Data were analyzed by using a normality test, homogeny test, and t test. Based on the analysis of data obtained by the average result of the students comprehension of mathematical concept experimental was 87.30 and 68.04 the control class student. Hypothesis testing using one side of t-test with MINITAB software, acquired P-value less than , so it can be concluded that the student comprehension of mathematical concept by applying cooperative learning model Snowball Throwing better than student comprehension of mathematical concept that applying conventional learning on student eightth grade at Junior High School 17 Padang.]]>
